Improving The Evidence Combination Formulas of D-S Evidential Theory in Medical Information Fusing

摘要

One of the key technique in information fusion research is to fuse incomplete information acquired from multi-sensors using D-S Evidential Theory. Because of the shortcomings of D-S Evidential Theory, there are certain limitations in evidential theory applications. An improving method based on D-S Evidential Theory is put forward in this paper. A research is done in improving Yager combined formulas. From the comparisons, the result is obviously that the improving formulas are more advanced than the old ones. Furthermore the improving formulas have more value in theory and practice.
